<P>PROBLEM TO BE SOLVED: To provide a hybrid heat-radiating substrate including a metal core layer in order to keep heat-radiating performance of heat generating elements, an oxide insulating core layer having lower thermal conductivity than the metal core layer and integrally formed with the metal core layer by volume anodizing, and thermally weakened elements mounted on an oxide insulating core layer, thereby making it possible to protect thermally weakened elements even though heat generating elements and thermally weakened elements are mounted on a single substrate together. <P>SOLUTION: The present invention provides a hybrid heat-radiating substrate 100 including a metal core layer 110; an oxide insulating core layer 120 that is formed in a thickness direction of the metal core layer 110 to have a shape where the oxide insulating core layer 120 is integrally formed with the metal core layer 110, an oxide insulating layer 130 that is formed on one surface or both surfaces of the metal core layer 110, and a circuit layer 140 that is configured to include first circuit patterns 140-1 formed on the oxide insulating core layer 120 and second circuit patterns 140-2 formed on the oxide insulating layer 130, and a method of manufacturing the same. <P>COPYRIGHT: (C)2012,JPO&INPIT |
